1 Claim.

This invention relates to that class of invenhaving to do with scaiolds,seats, chairs and the like expressly designed and used by painters andwindow-washers to expedite safe v5.: completion of an appointed task.

am admittedly aware of types of seats and chairs have Being generallyconversant with the state of e prior art to which the invention relates,I the fact that various been designed and adapted for use to promoteexpeditious and safe window Washing. It follows, therefore, that it ismy primary aim to generally improve upon these eviously known structuresby providing one characterized by structural renements and distinctionscalculated to provide appreciable improvements such as transcend theprior structures and in so doing to promote economy, efficiency,stability and safety.

Briefly stated, the preferred embodiment of e invention is characterizedby the incorporation therein of an appropriately shaped seat arddesigned for dependability and comfort, id seat board being equippedwith a foldable back-rest for compactness and convenience, and

and fastening means complemental adaptation aptly iitted formaintainrther provided with ing the chair in an adequate manner on thewindow sill.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings. I

In the drawings, wherein like numerals are employed to designate likeparts throughout the me: Fig. l. is an elevational view of the improvedoccupant chair illustrating the preferred construction and the manner inwhich it is at'- tached.

back-rest folded down Fig. 2 is an elevational view with the chairdeched from the window sill and showing the to collapsed position.

Fig. 3 is a front view of the structure illuschair being removed from ewindow.

Fig. 4 is a top plan view illustrating principally the construction anddesign of the seat board and the clamping or retention means.

through the plate Fig, 5 is a transverse detail sectional View portionof the adapter or clamping bracket, the section being taken on the planeof the line 5-5 of Fig. 4.

Fig. 6 is a detail perspective view of an especialdesigned stabilizingclamping member.

Fig. 7 is a longitudinal sectional view on an enlarged scale, takenapproximately on the plane of the line l-1 of Fig. 4

Referring now to the drawings by distinguishing reference numerals, itWill be observed in Fig. 1 that the window frame is denoted as a unit bythe numeral 8 and the stepped window sill is distinguished by thenumeral 9. The chair is so constructed as to adapt it to lit thisstepped or conventional type window sill.

The seat board of the improved chair is denoted by the numeral I (i andis of appropriate proportions and material. It is here shown as being inthe form of a saddle and the rear end or cantle portion is provided atopposite corners with keeper notches II. The central forward extensionI2 which may be distinguished as the pommel is of suitable narrowedconfiguration and terminates in a straight-cut end I3 which constitutesan abutment and is designed to rest against the ledge portion in theangle 9a of the window sill in the manner shown in Fig. 1. Hence, thisextension constitutes a stabilizing pommel as well as a carrier for theclamping means.

The clamping and retaining means which cooperates with the extension orcantle I2 comprises essentially a hanger unit including a rectangularadapter plate I 4 terminating in a padded hook I5 to engage over theledge of the window sill as shown in Fig. l. As indicated in Fig. 5, theadapter plate which is longitudinally elongated and rectangular isformed with a longitudinal central slot IS to accommodate the threadedend of the bolt Il carried by the pommel I2. On opposite sides of thisslot, I provide spaced parallel teeth I8 which may be described asretaining or rack teeth. The thumb nut I 9 on the threaded end of thebolt is adapted to cooperate with a ratchet plate 2li. This ratchetplate is of suitable proportions and preferably square and provided onits bottom with ratchet teeth 2l to engage adjustably with the rackteeth I 8. In addition, there is a central aperture in` the plate toaccommodate the bolt and nut and in alignment with this are dependinglugs or detents 22 which serve as stabilizing and guide fingers andwhich slide in the longitudinal slot I6. It is evident therefore thatthis hooked adapter unit makes it possible to t the seat board to Windowsills of varying proportions. It is observed that the hook lies in aplane to cooperate eiiiciently with the abutment or terminal I3 of theextension` I2.

On the bottom of the seat board, I provide a pair of companion orcomplemental stabilizing cleats 23. These are in the form of verticallydisposed wooden cleats, the lower edges 23 are inclined to conform toand rest in a solid manner upon the adjacent surface of the stepped partof the window sill `as shown in Fig. 1. The inner ends 25 serve as restsand engage iirmly behind the angular shoulder 9b on the window sill.This makes for rigidity and safety of maintenance of the seat board. Inother words, it also Yprovides for balance and stability and insuresexpeditious application and effective maintenance.

The next part of the structure to be observed is the back rest 26.appropriately shaped and proportioned frame which includes vertical endmembers or frame pieces 21 which are attached by hinges 28 to the seatboard which have their lower end portions Vextending down into thekeeper notches Il.

With this arrangement, it is evident that a comfortable seat and backrest is -provided for theuser or occupant. Then too, when the device isnot in use, the backrest can be folded down against the seat board asshown in Fig. 2 to provide for compactness and convenience in handling,shipping and storage.

Admittedly, although there are no radical structural differencesl inthedevice herein illustrated, there are certain evident improvements andrefinements which, it is believed, warrant favorable reception by thetrade and unqualified endorsement by the average user.

This is in the form of an f clamp carrier, a

, It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details coming withinthe field of invention claimed may be resorted to in actual practice, ifdesired.

l'. claim: Y

In a structure of the class described, a seat board, a hinged back restattached thereto, said seat board being formed on its forward edge withan extension constituting a pommel and clampof thepommel and includingan attaching hook v and a slotted adapter plate, a bolt carried by Ysaid pommel and including a nut co-operable adapter plate, and a pair ofreinforcing cleats on the underside of said seat board, said cleatsterminating short of said extension, said adapter plate being formed onopposite sides of the slot with rack teeth, and a with said slottedratchet plate superimposed on said adapter plate and including lugsslidable in said slot and ratchet teeth co-operable with said rackteeth, said ratchet plate being further co-operable with said bolt;
